LATCH-LEVER.

Specification of Letters Patent.

Application led September 27, 1911.

Patented July 23, 1912.

Serial No. 651,651.

To all @Li/0m t may'concern:

Be it know nthat I, VViLLIAM C. AZBILL, a citizen of the United States,residing at North lNIcAlester, in the county of Pittsburg and State ofOklahoma, have invented certain new and useful Improvements inLatch-Levers, of which the following'is a specification, reference beinghad therein to the accompanying drawing.

This invention relates to latch levers and the principal objectof thesame is to provide a novel type of latch for the lever and also toprovide a novel type of operating mechanism for the latch. y

In carrying out the objects generally stated above, it will beunderstood, of course, that the essential features thereof aresusceptible of changes in structural arrangements and details, onepreferred and practical embodiment being shown in the accompanyingdrawings, wherein r Figure 1 is a view in side elevation of the improvedlatch. Fig. 2 is a vertical section through the latch. Fig. 3 is a viewof the end of the upper portion of the lever. Fig. f1 is an enlargedview of the upper portion of the lever shown in Fig. 3. Fig. is atransverse sectional view taken through the hand grip of the levers.

Referring to the accompanying drawings by numerals it will be seen thatthe improved lever comprises a bar 1 which is split intermediate itslength to form a housing 2 for the latch 3. The latch is of asubstantial elliptical shape and has its end portions 4 and 5 providedwith teeth, the teeth of the end portion L1 being formed upon the lowerface and the teeth of the end portion 5 being formed upon the upperface. A rack bar 6 passes through the housing 2 and is provided with atoothed slot 7 through which the latch passes. The latch 3 engages theteeth of the slot and is thus held in an adjusted position. A rod 8 isconnected with .the latch by means of a link 9 mounted upon the pin 10extending from the latch and the upper end of the rod is in pivotalconnection with a bell crank bracket 11 mounted upon the bar 1. Byrocking the bell crank the arm 12 is rocked to move the rod 8 and thusbringing the teeth of the latch either into or out of engagement withthe teeth of the slot 7 The arm 13 of the bracket is provided with anotched extension 14: adapted to be engaged by a catch 15, which isslidably mounted upon the bar 1 so that latch 3 may be locked in or outof engagement with the rack bar 6. The upper end of the bar 1 is reducedand a spring 16 is coiled about the same with the upper endpassing'through an opening formed through the bar. A hand grip 17 ismounted upon the upper end of the bar and the lower portion of the handgrip is provided with a socket 1S in which arm 19 of the bell crankbracket lits so that when the hand grip is turned the bell crank bracketwill be rocked to raise the arm 12 and to release the latch from therack bar. The lower end of the spring 16 engages the hand grip so thatit is normally held in a positionto retain the latch in engagement withthe rack bar. The hand grip is provided with a bridge 20 Athrough whichthe upper end of the bar 1 passes and the hand grip is held upon the barby means of the key 21. A collarl 22 is formed at the lower portion ofthe hand grip and is provided upon its opposite sides with lugs 23.Cushions 24 are secured to the hand grip and their lower ends areengaged by the lugs 23 so that when the hand grip is turned the cushionswill not slip out of place. A sleeve 25 incloses the lugs and the-lowerportions of the cushions and assists in holding the cushions in place.

In using this device the rack bar is mounted upon a support 26 and thebar 1 is pivotally connected with the support by means of the bracket 27with the latch engaging the rack bar. When it is desired to move thelever the hand grip is turned which rocks the bell crank bracket so thatthe rod 8 is raised thus rocking the latch and releasing said teeth fromthe rack bar. The lever can then be moved to the desired place and whenreleased the spring 16 will turn the hand gript-hus moving the latchinto engagement with the rack bar. the lever in the adjusted osition thelatch 15 is moved so that it wil enter the notch formed in the arm 13and is then secured by means of the nut 28.

What I claim is 1. A lever, arack for said lever, a tooth carried bysaid lever and adapted to engage said rack, a rod connected with saidtooth, a bell crank pivotally mounted upon said lever and having one armconnected with said rod, said lever having a reduced upper end, ahandgrip rotatably mounted upon the reduced end of said handle andprovided with a socket in which the remaining arm If it is desired tolock CIK of said bell crank lits, and u Spring carried by the reducedend of said lever and engaging said handgrip to normally hold said bellcrank in a position to hold Said tooth in engagement with said rack.

2A lever, a rack, a tooth adapted to engage said rack, a rod connectedwith Said tooth, a bell crank pivotally mounted upon said lever, andhaving one arm connected with said rod7 said lever provided with areduced upper end, ay Hut-sided handgrip provided With longitudinallyextending openings in its central portion7 a bridge separating saidopenings, said handgrip being mounted upon the reduced end ol' Saidlever with Said lever passing through said openings, and said bridge, acoller formed at the end of said handgrip and provided With a socket inWhich one arm of said bell crank fits whereby the turning of .saidhundgrip will move said bell crank, a spring mounted upon the reducedend of said lever engaging said handgrip to normally hold said handgripin a position to bring said tooth into engagement With said rack, andcushions carried by said handgrip.

3. A lever comprising a reduced end, a spring mounted upon the reducedend of said lever, a handgrip mounted upon the reduced end of Said leverand bearing against Said spring, one end of said spring engaging Said.handgrip and adapted to rotate said handgrip upon said lever7 a flangeat the end of said handgrip provided With lugs, cushions carried by Saidhaiulgrip7 and tittiug in said colla-r and between said lugs, saidcollar being provided with a socket., a bell crunk pivotally mountedupon said lever and having one arm entering said socket, a rod carriedby the ren'iziining arm of Said bell crank, e rack, and a tooth carriedby said lever' and connected with said rod and adapted to be broughtinto and out of engagement with said rack upon the turning oLl' saidhandgrip.

y ln testimony whereof I hereunto allix my signature in presence of twoWitnesses.
